SLUB CATCHER Filed Sept. 14. 1929 INVENTOR 00 45. 6 9651900671 ATTORNEYPatented July 7, 1931 UNITED STATES PATENT OFFICE LOUIS B. HASBROUCK, OFELMIRA, NEW YORK, ASSIGNOR TO ECLIPSE TEXTILE DE- VICES, INQ, OF ELMIRA,YORK, A CORPORATION OF NEW YORK SLUB CATCHER Application filed September14, 1929.

This invention relates to slub catchers, and aims to provide a slubcatcher particularly adapted for use on worsted yarns.

A slubcatcher embodying the invention has a spring blade mounted so thatit is drawn in to sever the yarn by the engagement therewith of slubs orother projections on the yarn.

The device provides for positioning slubs or other projections on theyarn so as to engage lo the blade, and for accurate adjustment of theblade for use with different sizes of yarn.

An illustrative embodiment of the invention is shown in the accompanyingdrawings, in Which:

Fig. 1 is a side elevation;

Fig. 2 is an end elevation; and

Fig. 3 is a plan view.

The slub catcher illustrated has a frame 10, from which projects acurved bed 11 across and partly around which a traveling yarn A isdrawn, as shown in Fig. 1. The bed 11 is made of hard material, such asporcelain, and may be cylindrical as shown, although the shape of thelower part of the bed is, of course, immaterial to the action of thedevice. On the outer end of a slightly resilient adjustable bracket orarm 12 secured to the frame 10 is mounted a plate 13 which is transverseto the line of travel of the yarn and to the upper surface of the bed.The plate 13 contains a bend near its outer edge so that its outerportion 14 is inclined toward the direction from which the yarn istraveling, while its main body 15 is either less inclined in saiddirection or substantially perpendicular to the line of travel of theyarn. Against the outer portion 14 of the plate 13 is secured the outerend of a spring blade 16, so that this blade tends under its own resil iiency to move away from the main body 15 of the plate 13 and to assume aposition in which it is inclined toward the direction from which theyarn is traveling. Such outward movement of the blade is limited by astop 17 which extends from the lower portion of the plate 13, and may beformed by a frame-like projection at the lower edge of the plate asshown. The blade 16 contains a bend near its lower edge, so that, whenit is in its normal pos1- tion against the stop 17 the portion 18 of theSerial No. 392,619.

blade near its lower edge is substantially perpendicular to the line oftravel of the yarn. The lower edge of the blade is preferably sharpenedas shown.

The normal distance between the edge of the blade and the bed should bejust sufficient to permit the yarn to travel freely between them.Accurate adjustment of this distance is obtained by adjusting theposition of the plate 13 by means of a screw 19 threaded into the frame10 and having a head bearing against the arm or bracket 12. Acompression spring 20 holds the arm or bracket 12 in firm engagementwith the head of the screw 19.

In the operation of the device, slubs and other projections on the yarnare turned upwardly by the drawing of the yarn across the curved bed 11.Such slubs and projections, therefore, strike the lower edge of theblade 16, whereupon the travel of the yarn draws the blade inwardlytowards the plate 13. Because of the inclination of the blade and theportion 14 of the plate 13 to which it is attached, this inward movementof the blade swings its lower edge against the bed so that it severs theyarn.

W hat I claim is:

1. A slub catcher, comprising a bed across which a traveling yarn isdrawn, and a bent resilient blade having a body portion inclined towardsthe direction from which the yarn is traveling and an end portionsubstantially perpendicular to the line of travel of the yarn andterminating in an edge slightly spaced from said bed.

2. A slub catcher, comprising a bed across which a travelin yarn isdrawn, a rigid plate extending toward said bed and having an outerportion inclined towards the direction from which the yarn is traveling,a resilient blade having one of its ends secured against said inclinedportion of said plate and its other end opposed to said bed, and a stopon said plate limiting movement of said blade away from the plate andthe bed.

A slub catcher, comprising a bed across which a traveling yarn isdrawn, a rigid plate extending toward said bed and having an outerportion inclined towards the direction from which the'yarn is traveling,a resilient I blade having one of its ends secured against said inclinedportion of said plate and its other end opposedto said bed, a stop onsaid plate limiting'moveinent of said blade. awa
